Causes of mid-term abortion of test tube babies in Hebei Second Hospital

IVF is a kind of assisted reproductive technology, which can help couples who cannot conceive naturally realize their reproductive dreams. However, in the process of IVF, mid-term abortion is a worrying problem. Medium term abortion refers to abortion between 12 and 28 weeks of pregnancy, which may bring great psychological and physiological pressure to couples. The following will explain the reasons for mid-term abortion of IVF in Hebei Second Hospital from several aspects.

1. Embryo quality problems

Embryo quality is one of the key factors in the success rate of IVF. Embryos with large differences in embryo quality are prone to mid-term abortion. Poor embryo quality may be caused by gene mutation, chromosome abnormalities, etc. In addition, IVF embryos undergo a series of treatments before implantation, such as in vitro culture, embryo evaluation, etc. Improper operation or improper environment will also lead to the decline of embryo quality, which will lead to mid-term abortion.

About 30% of IVF mid-term abortion cases in Hebei Second Hospital are caused by embryo quality problems.

2. Abnormal uterine structure

Abnormal uterine structure is another common cause of mid-term abortion in IVF. Structural abnormalities such as endometriosis, uterine mediastinum and uterine fibroma will affect the implantation and growth of embryos and increase the risk of mid-term abortion. In addition, weak endometrium and ischemia will also lead to insufficient nourishment and support of the embryo, which will lead to mid-term abortion.

According to the research of Hebei Second Hospital, about 20% of mid-term abortion cases are related to abnormal uterine structure.

3. Immunization problems

The abnormal activity of the immune system is also one of the reasons for the mid-term abortion of IVF. Abnormal immune system will lead to maternal rejection of the embryo, making it impossible for the embryo to develop normally in the womb. Immune problems may be manifested as autoimmune diseases, anti embryonic antibodies, etc.

About 15% of IVF mid-term abortion cases in the Second Hospital of Hebei Province are related to immune problems.

4. Pregnancy complications

Pregnancy complications are also one of the reasons for mid-term abortion of IVF. Complications during pregnancy include hypertensive disorders during pregnancy, gestational diabetes, and oligohydramnios. These complications will bring risks and pressure to the embryo and mother, and increase the possibility of mid-term abortion.

According to the data of Hebei Second Hospital, about 10% of mid-term abortion cases are related to pregnancy complications.

summary

To sum up, the causes of IVF mid-term abortion in Hebei Second Hospital mainly include embryo quality problems, abnormal uterine structure, immune problems and pregnancy complications. Mid term abortion is a worrying problem in the process of IVF, which is a huge psychological and physiological blow to couples. In order to improve the success rate of IVF, doctors need to fully assess the individual situation of patients, identify and deal with potential risk factors, so as to reduce the occurrence of mid-term abortion.
